。[Claim for Utility Model Registration] A magnet roller is provided in the opening of the housing corresponding to the photosensitive drum, and a two-component developer is supplied to the magnet roller by a paddle roller provided in the housing, and the layer thickness is A thin layer of developer having a predetermined thickness is formed by a regulating member, and the toner is supplied to a nip portion relative to the photoreceptor drum, and the toner is caused to fly toward the electrostatic latent image formed on the photoreceptor drum. In the apparatus, the paddle roller for supplying the developer to the magnetic roller is composed of a main body portion having a certain developer transporting ability and a portion having no developer transporting ability on both sides of the main body portion. In addition, the length of the main body of the paddle roller is formed to be shorter than the image area of the photoreceptor drum, and the length of the roller is formed to be longer than the image area and shorter than the length of the magnet roller. A developing device characterized by:
